Switching to Angular 2

At the time of this posting, this book had a combined rating of 1 star, so you can see there is a little difference of opinion here! It wasn't easy deciding to buy the book with the 1 star rating staring at me, but I thought I would take the leap because of my high regard for the angular2-seed project with the author has created on GitHub. I'm glad I did because I have had several aha moments while reading the book and I'm only 60% of the way through. So far I've found the discussions of using OnPush data binding with immutable data and the specifics of injection to be the best I've read anywhere. I don't think the book is perfect -- some terms are used before they are defined, for example, but overall I think the perspective provided by this book to be extremely valuable, especially in providing a deep understanding of why the changes from Anular1 are what they are. Please note the target audience is developers who have had experience with Angular 1 (thus the 'Switching' in the title). This eliminates the bane of many tech books that waste time and space reviewing fundamental concepts, so that the meet of the subject is often short-changed. I'm very grateful that Minko did not take that approach here.

This book is NOT for "learning Angular", it is for people who already have a pretty good understanding ofAngular 1 and Angular 2. If you are a beginner, get an Angular2 book.With that said, this book is GREAT for finding out the "why" and "how" to switch from Angular 1 to Angular 2.It does have a few code errors, but if you already know Angular, you will see the error, ignore it and keep moving.

I had misunderstood the title thinking it would be an Angular 2+ book. It's focused on going to 2 from 1. Major portions talk about history of 1. Boring if you don't care.

Good book. Simple and easy to follow

Outdated, completely useless due to Angular 2 and Typescript versioning. This rating may be more about the Angular 2 and Typescript effort going on out there. The code version changes are so drastic you have to completely rewrite your work. This book used an Angular2 seed which sheltered the need to keep up with changes. That probably did more harm than good. Learning and building on deprecated code is a fruitless activity. Even if your book intent is to explain the differences in the versions you can't compare a moving target.

If you are looking for a complete understanding behind the why and what of Angular 2 (as contrasted against Angular 1), this book is for you. The background and flow provide a gradual learning process that walks you through how things came to be, starting with fundamental concepts behind component based architecture, talking through change detection in 1.x leading to why getting "In the zone.js" with Angular 2 is superior and smarter.One of the biggest challenges for Angular 1.x developers or anyone coming to Angular 2 fresh is grasping TypeScript. Although not required, the development story is vastly improved with it. Expect to get an excellent crash course on TypeScript here; very helpful to newbies and intermediates alike as a solid refresher. An overview of the `typings` tool to keep things in good shape as well as a reality check on what ambient type definitions are is also included.Heard the Dependency Injection is revamped? Yeah, well that's covered too right down to the nitty gritty with child injectors and visibility of injected services to child components. Sound scary? Don't worry, you'll learn all about it and love it, trust me.This is **not** a "let's build an incredibly sophisticated application with Angular 2 and I'll show you examples of how to do it", but rather "let's understand every fundamental piece with examples to help you build that sophisticated application with Angular 2".I find the background information, detail, and flow of this book to be incredibly well written to establish a solid understanding of the subject matter. Much applause and thanks to Minko for the time in preparing this material and to Misko for keeping him straight!

Thanks for author. This book is very clear and full of useful examples.Unfortunately, my JS knowledges could be better, and I didnt understand some code like: return this.developers.filter(u => u.githubHandle === username).pop();orthis.githubAPI.getUser(model.githubHandle) .catch((error, source, caught) => { console.log(error) return error; }) .map((r: Response) => r.json()) .subscribe((res: any) => { let dev = new Developer(); dev.githubHandle = res.login;.......All of functions like map, pop, subscribe are not clear for me.So a question to author.Where can I find a good definition, how to use this programing strategy in a proper way?And also, I was looking in different sources a definition for arrow function, but Im still bad there as well.Thanks!

Ottimo libro , inizia a fare un resoconto su typescript e poi si addentra in angular 2 con esempi, ottimo per iniziare

Not much helpful content.. Except beginning two chapters
